note 18004 added to function.md5

maybe a foolish notice: md5 can't work on array and objects althought it will not occure error message when use md5($my_array) or md5($my_object). in fact it return with md5("Array") and md5("Object"), so the return value alway be the same value... -- http://www.php.net/manual/en/function.md5.php http://master.php.net/manage/user-notes.php?action=edit+18004 http://master.php.net/manage/user-notes.php?action=delete+18004 http://master.php.net/manage/user-notes.php?action=reject+18004
